Patent DE-3713312-A1 (DE)
Title: Controllable AC source for gas-discharge paths for light production and ozone production
Inventor: FENDER MANFRED PROF DIPL ING
IPC: H05B41/288
Filed: 1987-04-18
Abstract: In the case of light production using gas-discharge lamps, ozone production by means of assisted discharges in oxygen and similar gas-discharge paths, a controllable electrical power supply is required in order to optimise operation. As a result of the arcing characteristics of the load and the requirement for an electrical power supply which is resistant to short circuits in the case of a flashover, ballast inductances, high-reactance transformers etc. are connected between the infinite mains and the load. In consequence, only one specific operating point is possible and large power losses occur. A suitably controlled power electronics device which operates using triangular waveform or even rectangular waveform currents avoids these disadvantages. The efficiencies of the electrical power supply and those of the load also increase. In the case of ozone producers (ozone generators), the power electronics device furthermore multiplies the power of the apparatus (capacitive load) by means of radio-frequency operation. Production-dependent imbalances (asymmetries) of gas-discharge lamps can be regulated out by the electronics.

Patent DE-3719219-A1 (DE)
Title: Method for producing a printed-circuit board
Inventor: JOENS ROBERT
IPC: H05K3/06
Filed: 1987-06-09
Abstract: Method for producing a printed-circuit board which on both sides has conductor (wiring) tracks with plated-through connecting points. Such printed-circuit boards are principally produced using the MR method. The printed-circuit boards have, as required, contact pads to which pressure elements are applied and which therefore have a gold support (locating) pad. This gold support pad is expensive and is therefore to be replaced by a graphite support pad. In order to be able to apply a graphite support pad to a printed-circuit board at specific contact points of a printed-circuit board, which is produced using the MR method, in a technically acceptable quality and a cost-effective fashion, it is necessary to print a graphite resist onto the printed-circuit board as early as after the chemical copper-plating of the printed-circuit board in order to produce the connection conductivity. The graphite resist which is to be used must have a prescribed chemical stability.

Title: Means for securing a pipe connection against torsional forces, and process for producing pipe-connection pieces which are secured against torsion
Inventor: THOMAE RUDOLF DIPL ING
IPC: F16L13/14
Filed: 1987-08-29
Abstract: Pipe connections comprising pipes of different degrees of material hardness, which are plugged together telescopically at the connection point and are produced by means of a pressed-on clamping ring, are indeed resistant with respect to loading by tension, compression and vibration, but they are susceptible with respect to torsional forces.   In order to secure against torsional forces, the end of the interior pipe consisting of the harder material is provided, on the outer side, with a grooved arrangement, the telescopically plugged-together region of the connection being lengthened by approximately 50%. In addition to the clamping ring, a securing ring, having a slightly smaller internal diameter than that of the clamping ring, is pressed onto the pipe connection over the region of the grooved arrangement, the securing ring being only approximately half as long as the clamping ring. The process exhibits the individual manufacturing stations for producing pipe-connection pieces according to the invention.

Patent DE-3740294-A1 (DE)
Inventor: HANK DIETRICH DR ING
IPC: F26B13/12
Filed: 1987-11-27
Abstract: Apparatus for regulating the temperature of a web of material, which is to be printed on, in a web drier arranged after a printing machine serves to keep the web temperature at a maximum permissible value. This is achieved through a fixed value regulation, in which the web speed (vB) is influenced in dependence on temperature deviation. For this purpose, a sensor (2) for measurement of the web temperature is arranged in the web drier (1) near the web outlet and - in conjuction with a regulator (4) and a setting drive (5) for the setting of the web speed - forms the regulating apparatus. The starting and speeding-up of the rotary printing machine can thereby be so matched to the heating-up of the drier that a minimum of printers' waste arises. <IMAGE>

Abstract: Defence equipment is used by egoists to achieve their own ends, even at the cost of the innocent. This misuse of modern technology can be prevented by suitable countermeasures without having to kill the enemy. Foaming plastics are used for this purpose which can also be mixed with two-component adhesives depending on the application in order thus literally to tie up the enemy, together with his equipment, and to render him incapable of destruction. The defence techniques described here enable completely new defence strategies, have scarcely any effects on the environment, and make it possible to resolve local conflicts quickly and safely.

IPC: G01C11/00
Filed: 1988-02-22
Abstract: The invention relates to an arrangement and a method for determining the length of flight of bodies moving on flight paths, jump trajectories and projectile trajectories, in particular for determining the length of jumps in ski jumping. The aim is to provide an arrangement and a method in which mobile equipment can be used without additional devices on the moving bodies to determine length in a manner which is objective and can be subsequently checked, and in the case of which a high interference immunity is ensured at the same time. The object is achieved when the current surface profile is geodetically determined before the length, the ground scene is followed by the survey (mapping) camera, for the pictures of which the data of the inner and outer orientation are known, and these data are stored, supplemented by the position values of the camera positions, and used to determine the length. The result can subsequently be determined or monitored afresh at any time.

Title: Method for controlling brushless electric motors and control circuit therefor
Inventor: KOTHE KARL-PETER DIPL ING
IPC: H02P6/15
Filed: 1988-06-04
Abstract: In order to control a brushless D.C. motor (1), use is made of a three-phase driver signal delivered by a rotor position sensor (3) for driving transistors (7) in a transistor bridge circuit (6). The transistor bridge circuit (6) supplies the windings (5a, 5b, 5c) in the stator (4) of the D.C. motor (1) with current pulses. The commutation point is brought forward by 60@ above a predetermined level of an operating characteristic, for example above a predetermined rotational speed level. This is produced by an alteration of the assignment of the rotor position signal to the drive signal for the transistors (7), so that, in each case, the same transistor combination is switched on as would come next without precommutation as the next-but-one transistor combination. <IMAGE>
